Addressing · Beginner
The widely deployed 32-bit version of the Internet Protocol. Addresses are usually written as four decimal numbers from 0 to 255, separated by dots.
This is the older address format still used almost everywhere. Because 32 bits do not provide enough public addresses for every device, networks reuse private ranges and translate them.
Example: 203.0.113.10 is a documentation address in this format. 192.168.0.1 is a private address in the same format.
Common misconception
- Dotted decimal is only a way to write the address. The address itself is a 32-bit number.
